CoJobus palliatus, Peters. 



Dr. Peters has described a Colohus from Zanzibar, under the name 

 of Colobus paUiatus, from a yonng specimen that was living in the 

 Zoological Gardens at Hamburg, and is now in the Hamburg ]\lu- 

 seum. The description agrees in many particulars with the Colobus 

 Kirl'ii, received from Dr. Kii-k, which I described and figured in the 

 ' Proceedings of the Zoological Society' for Feb. 1868, p. 18U, t. 15. 

 "VMien Dr. Kirk sent that skin, he informed me he had sent a young 

 li\ing specimen to Hamburg, on its way to our Zoological Gardens 

 in England. I have every reason to believe that the animal de- 

 scribed by Dr. Peters is the one sent (though his name is not men- 

 tioned) by Dr. Kirk. It is most probably a specimen of the species 

 which I have described, the difference in the description probably 

 arising from the animal being immature and having been kept in 

 confinement. — J. E. Gray. 



HADROSATJRtrS. 



Mr. Waterhouse Hawkins has obtained permission of the Academy 

 of iS^atural Sciences of Philadelphia to erect, at his own expense, in 

 the hall of the Academy a model of the skeleton of the Hadrosaiiras, 

 in accordance with the restoration of Dr. Leidy. 



Living Crinoids of the North Sea. By Dr. Michael Sars. 



Prof. Michael Sars has published a cpiarto monograph, in French, 

 describing lihizocrinus lofotensis and the pentacrinoid states of Aa- 

 tedon Sarsii. The Rhizocrinus was discovered by M. G. 0. Sars at 

 Lofoten Island. It was at first believed to be the pentacrinoid state 

 of an undescribed Antedon ; a more careful examination showed that 

 it is a Lily Encrinite, and more nearly allied to the genus Bourgueti- 

 crinus of Dujardin and Huppe. 



Prof. Sars shows how the pentacrinoid form of Antedon Sarsii 

 differs fi-om the same form of A. rosaceas, described by Prof.Wyville 

 Thomson and Dr. W. Carpenter ; and he states that the larvae of the 

 genus Antedon undergo six distinct transformations. These animals 

 are illustrated with six plates full of most minute details of the struc- 

 ture, habit and development, and the physiology and morphology of 

 these most interesting animals, so important as explaining the veiy 

 numerous fossil Crinoids. 



New Alligator from New Granada. 



Mr. Edward Cope, in the ' Journ. of the Acad, of Natural Sciences 

 of Philadelphia,' 1868, p. 203, describes an Alligator, from Magdalena 

 River, in I^ew Granada, under the name of Perosuchiis fusciis, pecu- 

 liar for having only two claws on the front feet, and fleshy eyebrows
